Description

Improved billet feeding rack

Technical Field

The utility model relates to a steel billet material loading rack belongs to the equipment before the steel rolling technical field heating furnace.

Background

The billet feeding rack is used for storing and transporting billets; and the steel billet conveying device is matched with a steel moving machine, a furnace entering roller way and the like to finish the task of conveying the steel billets into the heating furnace. As shown in figure 1, the arrangement and relative position relationship of the billet feeding rack, the steel moving machine and the furnace entering roller way are shown.

The billet feeding rack has the functions of: firstly, buffering a blank feeding process stage before a heating furnace, and storing a certain amount of steel blanks; secondly, the movable beam/the fixed beam supports the steel billet, and the movable beam moves relative to the fixed beam to realize the stepping movement of the steel billet to the front end; and thirdly, controlling the feeding of the steel billets to prepare materials for the subsequent process.

In order to meet the bearing requirement of a certain length of steel billets, a plurality of groups of movable beams and fixed beams are generally transversely arranged on a feeding rack; each group comprises a set of static beam parts and a set of dynamic beam parts; the side surface of the front end of each set of static beam is provided with a set of steel blocking hook parts.

Wherein, the static beam and the steel rail are used for bearing steel billets. The top surfaces of the static beam and the steel rail are used as billet bearing surfaces and are on the same horizontal plane. The static beam and the steel rail are respectively installed on the civil foundation in a fixed mode through a steel structure support and a rail pressing plate. The front part of the static beam is provided with a V-shaped groove structure for collecting the falling steel billets. The inclined plane of one side of the V-shaped groove structure and the horizontal section of the rear part form a turning angle structure. When the center of gravity of the section of the steel billet on the static beam crosses the turning angle, the steel billet can slide into the bottom of the V-shaped groove along the inclined plane under the action of gravity and then stop.

As shown in figure 2, the steel blocking hook is arranged on the side surface of the static beam and is used for controlling the process of sliding the steel billet moving to the V-shaped groove. The tail of the steel resistance hook is connected with the static beam by a trunnion vertical to the side surface of the static beam, and the steel resistance hook can swing around the trunnion. The vertical surface of the front end structure of the steel blocking hook is a blocking surface of the billet. The position of the billet blocking surface exceeds the vertex position of the turning angle of the static beam for a certain distance. Can swing up and down along the trunnion under the action of the steel blocking hook driving mechanism. When the front end and the related parts of the steel blocking hook fall into the inclined plane outline range of the V-shaped groove structure of the static beam, the blocking of the vertical structure at the front end of the steel blocking hook on the steel billet can be removed, and the steel billet is allowed to slide on the inclined plane of the V-shaped groove.

The movable beam is used for bearing and conveying steel billets. The length of the movable beam is matched with the total length of the static beam and the steel rail. The outer corridor and the size of the front end of the movable beam are matched with the V-shaped groove of the static beam; when the top surfaces of the movable beam and the static beam are flat, namely the movable beam moves to a low position, the outline of the front end of the movable beam is positioned in the range which can be covered by the inclined surface of the V-shaped groove of the static beam. The lower part of the front end of the movable beam is connected with the synchronous beam; a plurality of movable beams are transversely connected into a whole through the cross beam, so that the requirement of synchronous movement of all the movable beams in the feeding rack under the condition of a single driving source is met. The tail part of the movable beam is provided with a roller mechanism, and a roller of the roller mechanism can horizontally roll on the guide rail. The movable beam, the bearing seat, the eccentric shaft, the roller and other parts form a crank-slider mechanism in mechanics. When the eccentric shaft of the eccentric lifting mechanism does a circular positive rotation motion, the movable beam is used as a connecting rod component and is matched with the static beam under the driving of the movable beam, and the billet loaded on the upper part is transferred forwards through the alternate circular motion of supporting and descending on the static beam. The tracks of the steel billet bearing surfaces of the movable beam body are different, the step pitch at the front end close to the feeding rack is larger, and the step pitch at the rear end is smaller; generally, the design aspect is comprehensively considered in combination with the reasonableness of the structure and the power configuration of the movable beam body, and the maximum step size of the related part at the front end of the movable beam body does not exceed 1/2 of the side length of the section of the steel billet; therefore, the stroke of the side length dimension of the section of the billet can be completed by more than one cycle of stepping.

The steel moving machine is used for moving the steel billets between the steel billet feeding rack and the furnace entering roller way. When the fork head of the main functional component swings, the steel billet in the V-shaped groove of the static beam is transferred and then is flatly placed on the roller surface of the furnace roller way.

The furnace roller way mainly has the function of sending the steel billet into the heating furnace.

In the automatic operation before the steel billets enter the furnace, according to the process requirements, the length and weight measuring process is required to be carried out on a single steel billet before the steel billet enters the furnace. Therefore, only one billet can be released each time in the process of transferring the billet from the billet feeding rack to the furnace roller way, otherwise, the length and weight measuring procedures of the billet are adversely affected, and the redundant billet on the furnace roller way needs to be removed through manual intervention.

The equipment related to the original billet feeding rack and the blanking process is characterized in that the relative position of a steel blocking hook and a static beam is mainly adopted. A billet blocking surface of the steel blocking hook of the original billet feeding rack is close to a turning angle of the static beam; the center of gravity of the cross section of the foremost steel billet carried on the static beam is positioned behind the turning angle. Therefore, the process phenomenon is that even if the front end and the relevant part of the steel blocking hook fall within the inclined plane range of the V-shaped groove structure of the static beam, the steel billet cannot freely slide to the inclined plane of the V-shaped groove. FIG. 3 shows the position relationship between the static beam and the steel-blocking hook of the loading rack for the raw steel billet

The process of steel billet falling under the condition of limited structure comprises the following steps: when the movable beam is driven by the driving mechanism, the billet alternately steps forwards on the movable beam and the static beam of the feeding rack. When steel billets are needed by the furnace entering roller way, the steel blocking hooks on the side surfaces of the static beams swing downwards under the action of the driving mechanisms until the static beams retreat into the outline of the V-shaped groove of the static beams. The moving beam makes the steel billet fall into the V-shaped groove at the front end of the static beam through a plurality of circulating stepping actions, and then the steel billet is lifted by a fork head of the steel moving machine and moved to a furnace roller way.

When the steel billet steps on the feeding rack, the stepping posture of the steel billet is not in an ideal state, and the steel billet cannot be corrected in the moving direction theoretically due to the reasons that the position of the length direction of the steel billet is not vertical to the longitudinal direction of the movable beam and the fixed beam, the steel billet is bent to a certain degree, and the like, so that the two ends of the steel billet are asynchronous when the steel billet reaches the front end turning angle of the fixed beam. Meanwhile, the movable beam steps one action cycle and cannot position the steel billet once; in the process, a plurality of stepping circulating actions are executed to ensure that the steel billet on the movable beam is directly shaken and placed and slides into the V-shaped groove at the front end of the fixed beam. In the process state, although the steel blocking hook can be lifted in advance, the process of closing and aligning the steel billets is implemented, and then the steel blocking hook is released to implement the process of throwing the steel billets into the V-shaped groove of the static beam; however, when the steel blocking fishing is put down, the moving beam moves to release the billet steel to be in the billet steel position and be in an unconstrained state. Under the unconstrained process condition, the possibility that two billets fall into a V-shaped groove of the static beam simultaneously exists, so that the normal control process of the billet stepping, releasing and transferring process sequence is damaged. Then, no matter two steel billets are transferred by the fork of the steel moving machine at the same time and are put into a furnace roller way for further treatment, or the treatment is carried out in a static beam V-shaped groove in real time, manual intervention is needed to implement the removing treatment process, so that the rhythm of the normal automatic operation process is influenced, and the operating condition of automatic conveying of the steel billets between the feeding rack and the steel moving machine cannot be formed. FIG. 4 shows the process of the billet falling process of the billet feeding rack

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model discloses an improved billet feeding rack.

In order to achieve the above purpose, the utility model discloses a steel billet material loading rack

The method comprises the following steps:

a static beam; the front part of the static beam is provided with a V-shaped groove structure for collecting the falling steel billets;

the inclined plane at one side of the V-shaped groove structure and the horizontal section at the rear part form a turning angle structure;

the steel blocking hook is arranged on one side of the static beam; a trunnion vertical to the side surface of the static beam at the tail part of the steel resisting hook is connected; the steel blocking hook can swing around the trunnion under the action of the driving mechanism;

the vertical surface of the front end structure of the steel blocking hook is a blocking surface of the billet; when the front end and the related parts of the steel blocking hook fall into the inclined plane outline range of the V-shaped groove structure of the static beam, the blocking of the vertical structure at the front end of the steel blocking hook on the steel billet can be removed, and the steel billet is allowed to slide on the inclined plane of the V-shaped groove.

The connection and movement position relation between the static beam of the improved billet feeding rack and the steel blocking hook is that the steel blocking hook is arranged on the side surface of the static beam; the tail part of the steel blocking hook is connected by a trunnion vertical to the side surface of the static beam; the steel blocking hook can swing around the trunnion under the action of the driving mechanism. When the steel blocking hook swings and descends to be at the lowest position, the relevant position of the steel blocking hook is located in the range of the inclined plane outline of the V-shaped groove structure of the static beam, and the condition that the steel billet can slide is formed.

The steel blocking hook structure and the turning angle of the static beam are in a position relation that the position of the billet blocking surface exceeds the vertex position of the turning angle of the static beam for a certain distance. The distance between the billet blocking surface and the turning angle peak of the static beam is determined to be about the length of a billet section 1/2 side plus the bending size of the billet. When the steel billet with multiple section specifications needs to be adapted, the distance is required to meet the size requirement of the steel billet with the multiple section specifications, and the section gravity center of the steel billet with the large section specification is kept to be still outside the position of the vertex of the turning angle of the static beam.

The shape and the size of the front end of the movable beam are matched with those of the V-shaped groove of the static beam, and the outline of the front end of the movable beam is within the inclined plane range of the V-shaped groove of the static beam. The movable beam only defines and undertakes the functions of conveying and arranging steel billets; the falling of the steel billet to the V-shaped groove of the static beam is always controlled by the steel stopping hook, so that the moving beam only conveys the steel billet when the steel stopping hook is lifted.

The moving position relation among the steel billet, the steel hook resisting structure and the static beam is that when the steel hook is lifted and the steel billet is placed on the static beam, the gravity center point of the section of the steel billet exceeds the top position of the turning angle; when viewed from the section of the steel billet, one part of the two sides of the gravity center of the bottom edge of the section of the steel billet is positioned on the horizontal section of the steel stopping hook, and the other part is still positioned in the horizontal section of the front end of the static beam. When the front end and the related parts of the steel blocking hook fall into the inclined plane outline range of the V-shaped groove structure of the static beam, the blocking of the vertical structure at the front end of the steel blocking hook on the billet can be removed, and the billet can automatically slide on the inclined plane of the V-shaped groove to the valley bottom under the action of gravity to stop.

2. Improved billet falling process of billet feeding rack

Under the conditions, the steel billet stepping and sliding mode and process towards the V-shaped groove at the front end of the static beam are as follows: when the steel blocking hook is lifted, the horizontal section at the front end of the steel blocking hook is flush with the top surface of the static beam. The movable beam is matched with the static beam under the action of the driving mechanism, and the steel billets are transferred forwards in a stepping mode in the circulating process of alternately lifting and dropping the steel billets loaded on the static beam. The steel billets are stepped to the steel stopping end face of the steel stopping hook, and the second steel billet in sequence is made to be close to the first steel billet. When the V-shaped groove at the front end of the static beam is lack of steel billets, a single steel billet throwing process can be implemented. Putting down the steel blocking hook, and allowing the first steel billet to slide into the V-shaped groove of the static beam; the gravity center of the second steel billet is still in the horizontal section at the front end of the static beam and cannot fall into the V-shaped groove by means of self weight; thereby realizing the steel falling action of only allowing one steel to enter the V-shaped groove.
